Answer:
A = -10
Step-by-step explanation:
Combine multiplied terms into a single fraction find common denominator etc etc.
Answer:
C. 0
Step-by-step explanation:
–4j^2 + 3j – 28 = 0
The discriminant is b^2-4ac if >0 we have 2 real solutions
=0 we have 1 real solutions
<0 we have 2 imaginary solutions
a = -4, b =3 c = -28
b^2 -4ac
(3)^2 - 4(-4)*(-28)
9 - 16(28)
9 -448
This will be negative so we have two imaginary solutions.
Therefore we have 0 real solutions
7x10^4
Because there are 4 sets of 10
Growth rate = 200% each year
SO population becomes twice in each year
After 20 years, population = 5* 2^20 = 5242880
(Assuming no deaths occur)
